A submarine is 75 feet below sea level. It descends another 25 feet every 10 seconds for 3 minutes. What integer represents the submarines current location?

Assumptions and givens:
  • Let m be the number of minutes
  • 10 seconds is 1/6 of a minute, 6 (10) seconds blocks per minute * 3 minutes = 18 (10 second blocks)
  • Below sea level is a negative number
Current depth:
-25(18) - 75
-450 - 75
-525
